        One November night in the year 1782, so the story runs, two brothers sat over their winter
        fire in the little French town of Annonay, watching the grey smoke-wreaths from the hearth
        curl up the wide chimney. Their names were Stephen and Joseph Montgolfier, they were
        papermakers by trade, and were noted as possessing thoughtful minds and a deep interest in
        all scientific knowledge and new discovery. Before that night—a memorable night, as it was
        to prove—hundreds of millions of people had watched the rising smoke-wreaths of their fires
        without drawing any special inspiration from the fact.
